This behavior is controlled by a property on the binding called Update Source Trigger.It defaults to the value "Default", which basically means that the source is updated based on the property that you bind to.The command that sets the property 'Is Eco Generated' is a command on the View Model.Hi Odd Veibust, Do you set the value of the 'Is Eco Generated' property from the UI or from code behind?The only constraint when using this class is that instances of the collection must be created on the UI thread, so that events are raised on that thread.In the previous example, the only thing to change to make the collection modifiable across threads is the instantiation of the collection in the View Model : to raise the event when the collection is modified from the main thread can cause unpredictable behavior.This lightweight toolkit is the most popular Model-View-View Model (MVVM) framework for platforms such as Windows Presentation Foundation (WPF), Silverlight, Windows Phone, Windows Store, Xamarin.
